What is Determination of Polycyclic Aromatic Hydrocarbons in Vegetable Oils by Caffeine Complexation and Glass Capillary Gas Chromatography about?

Glass capillary gas &romatographJi was used for the determination of polycyiic aromatic hydrocarbons (PAHs), ReprodueiMe PAH proEles were obtained from vegetable fats and oils by complexing them with caffeine in formic acid solution, The caffcine-complexabie materials were then separated by column liquid and thin-layer chromatography, respectively. Glass capiihuy gas chromatographic results for PL4Hs specified by the U.S. Environmental Protection Agency were obtained after split injection within about 25 min. Quantitative and .qualitative results are given for several commercial vegetable oils\_ Recoveries of PAHs were in the range 68-95 v!\_ The detection limit was 16 ng of coronene in 100 g of oil. Grapeseed oil was shown to contain the lowest "polycyciic aromatic hydrocarbons burden"\_ ## INTRODUCI-IQN Polycychc aromatic hydrocarbons (PAHs) have been implicated in oncogencsis. The levei of their environmental occurrence is one of the variables used in determining the extent of voluntary or invohmtary human exposure to the combined action of carcinogens, procarcinogens and syucarcinogeus. Consequently, numerous analytical methods have been developed to monitor the total carcinoge
